I got slammed on my knee pretty hard tonight, when I was in quarter position and the guy I was rolling with was trying to reverse/throw me. Lifted me off the ground and dropped on my knee. I figured there would be pain and bruising, no big deal. But the problem I am having is I am having pain from my knee down my outer shin almost to my ankle, like alot of pain. More than my knee actually hurts. Is it something serious from those symptoms that anyone can think of? I'm about to go ice it.
